[FIX] point_of_sale: do not block if no COA

In case the COA is imported in the system, the `chart_template_id` of
the company remains empty while the accounting is usable. However, in
this case it's impossible to open a POS session.

We leave the warning in the POS config but avoid blocking the user.
